Secondary Surveillance Radar (SSR) based on multilateration principle and omni-directional antennae are operational today [1,2]. We proposed new algorithms to separate a mixture of overlapping SSR replies on a Å-elementsantennain previous works [3,4], other solutions were also proposed in the literature [5,6,7]. Unfortunately, all have either some shortcomings, or an expensive computational cost, or no simple practical implementation. Therefore, there is a need for reliable, simple, effective algorithms to separate multiple SSR signals. Real recorded signals in a live environment are used to demonstrate the effectiveness of the proposed techniques.

The paper main objectives are to identify an analysis model for development of integrated aquaponics with intensive beekeeping. The socioeconomic environmental impact assessment provides the opportunity to analyze the determinants of public attitude towards the use of multifunctional aquapson. In relation to the other agricultural production branches, beekeeping integrated into aquaponic systems is an environmentally friendly technology that does not use additional energy supply within the integrated production system and also recycles waste water from aquaculture through mechanical, biological filters and plant roots.

Pulmonary embolism occurs when thrombi enter the pulmonary arterial circulation. Most pulmonary embolisms are the result of deep venous thrombosis of the pelvic limbs, chest or pelvis, and, less commonly, the jugular veins or inferior vena cava. Venous thromboembolism includes deep vein thrombosis and pulmonary embolism. It is the third most common cardiovascular disease, with a total annual incidence of 100-200 per 100 000 population. INTRODUCTION: Acute pulmonary embolism is the most serious clinical presentation of venous thromboembolism. Overall, pulmonary embolism is a major cause of mortality, morbidity and hospitalization. Mortality in pulmonary embolism depends on haemodynamic impairment, age and co morbidities. The prognosis of patients with pulmonary embolism depends on two factors : underlying disease state plus diagnosis, and appropriate treatment. Approximately 10% of patients who develop pulmonary embolism die within the first hour, and 30% subsequently die of recurrent embolism. CASE PRESENTATION: In this presentation we present the case of a 49-year-old male patient without co morbidities, presented repeatedly to the Emergency Room for symptoms suggestive of pulmonary thromboembolism, who benefited from life-saving therapies due to timely diagnosis and appropriate treatment, with subsequent favorable outcome. CONCLUSIONS: The particularity of the case is that, on the one hand, the thromboembolic event recurred in a short time, on the other hand, the evolution was favorable in both cases, with complete recovery of right ventricular function and disappearance of pulmonary hypertension, despite the fact that the patient was non-compliant with initial anticoagulation therapy. This was due to both early diagnosis and timely administration of appropriate treatment.
